| Compound | Description |
|---|
| phosphoric acid | concise etchant is 37% H3PO4 |
| pyruvic acid | An intermediate compound in the metabolism of carbohydrates, proteins, and fats. In thiamine deficiency, its oxidation is retarded and it accumulates in the tissues, especially in nervous structures. (From Stedman, 26th ed) |
| taurine | A conditionally essential nutrient, important during mammalian development. It is present in milk but is isolated mostly from ox bile and strongly conjugates bile acids. |
| Glutathione | A tripeptide with many roles in cells. It conjugates to drugs to make them more soluble for excretion, is a cofactor for some enzymes, is involved in protein disulfide bond rearrangement and reduces peroxides. |
| 5-methyltetrahydrofolate | |
| glutamic acid | A non-essential amino acid naturally occurring in the L-form. Glutamic acid is the most common excitatory neurotransmitter in the CENTRAL NERVOUS SYSTEM. |
| s-adenosylmethionine | Physiologic methyl radical donor involved in enzymatic transmethylation reactions and present in all living organisms. It possesses anti-inflammatory activity and has been used in treatment of chronic liver disease. (From Merck, 11th ed) |
| cysteine | A thiol-containing non-essential amino acid that is oxidized to form CYSTINE. |
| Adenosine Triphosphate | An adenine nucleotide containing three phosphate groups esterified to the sugar moiety. In addition to its crucial roles in metabolism adenosine triphosphate is a neurotransmitter. |
| adenosine diphosphate | Adenosine 5'-(trihydrogen diphosphate). An adenine nucleotide containing two phosphate groups esterified to the sugar moiety at the 5'-position. |
| methionine | A sulfur-containing essential L-amino acid that is important in many body functions. |
| 5,6,7,8-tetrahydrofolic acid | RN given refers to (DL)-isomer |
| s-adenosylhomocysteine | 5'-S-(3-Amino-3-carboxypropyl)-5'-thioadenosine. Formed from S-adenosylmethionine after transmethylation reactions. |
| homocysteine | A thiol-containing amino acid formed by a demethylation of METHIONINE. |
